Hello everyone, I have a Solix 15GN2 and Mega 360 linked up together along with the Humminbird GPS/Heading puck. While on the Solix chart view my boat icon spins and jumps around the map not locking on to a position. Under the Solix settings I can set the GPS to internal and the GPS signal is fine with many satellites, when I change to the external GPS/Heading sensor I get no satellite signal just heading ( bad puck right ?) . I have also tried to use my Ultrex and its puck as the GPS/heading source but it also shows up with no satellite signal on the Solix. I thought the GPS signal was coming from the Ultrex control head not the MinnKota puck so do I somehow have a bad Ultrex GPS too ? Thoughts, ideas ? Thanks
